Application filed April 30, 921

To all whom it may concern:

eit known that I, JorIN H. GosNELL, a citizen of the United States,residing at W'hitewright, in the county of Grayson and State of Texas,have invented new and useful Improvements in Radiator Caps, of which thefollowing 'is a specification. v

This invention relates generally to caps or covers for radiators ofmotor vehicles, and is adapted particularly for use in connection withthe of tractors of that type wherein the filling opening is covered witha plate as distinguished from a screw top.

The primary object of the invention is to provide acap or cover for thefilling opening which facilitates filling of the radiator, minimizingthe opportunity for waste of water in such operation, which preventssplashing o' the water from the radiator, which enables steam or vaporsto escape when pressure within the radiator becomes excessive and yetwhich is so arranged as to promote condensation, thereby greatlyeconomizing the water in the cooling system.

A further object of the invention is to provide a cap of the characterstated of simple and inexpensive construction, easy of installation, andwhich so affects the water of the cooling system as to maintain thelatter at a low temperature, and which will prove thoroughly practicaland efficient in use.

With these and other objects in View, the invention consists of thefeatures of construction, combination and arrangement of parts,hereinafter fully described and claimed, reference being had to theaccompanying drawing, in which:

'- Figure 1 is a vertical sectional view taken through the radiator capor cover of myillustrating the manner in applied to a conveninventionand which the device is tional type of radiator, and

Figure 2 is a vertical sectional view taken through the cap at rightangles to the plane of Figure 1.

Referring now to the drawing 3 indicates the top portion of the radiatorof the vehicle, 4 the filling opening therein surrounded by theupstanding flange 5 as usual, and 6 indicates the spaced parallelretaining bars within the radiator and to which the closure cap of theradiator is usually secured as by a spring, chain, cord or othersuitable device.

upper portion of the body:7 is provided filling opening, of radiators aof openings Serial No. 465,781.

In carrying out the body 7 is provided, the lower end of said body beingopen and of such size asto surround the opening 4 of the radiator Thewith an inwardly and downwardly extending wall 8 constituting a funneland bafiie, the lower end of said wall being out awav'as at 9 to providea restricted opening. The upper edge of wall 8 engages the upper edgesof body 7 The upper end of body 7 is closed by a cap 10 hinged as at'llto one side of the body and'is 'adaptedto' I or closed"p osition, aswill be understood. This cap or cover is provided with a number 12 topermit steam to escape from the body 7. Y I

The means for securing the .bodyto the radiator includes a bolt 14: atits lower end to engage with the lower edges of bars 6 in the radiator;the upper end of bolt 13 passing through a suitable opening disposedcentrally of a cross member 15 secured to the inner walls of the funnelmember 8. A. nut 16 threaded upon the upper end of the said bolt enablesthe latter to be so adjusted thatthe body will be rig: idly clamped downupon the upperlsurface of the radiator. The lower edges of body 7preferably seat upon a gasket 17 surrounding'the filling opening 4, inorder that a tight joint between the body and the filling opening issecured.

After applying the body to the radiator opening, the filling of the saidradiator is readily facilitated, as poured very readily into the samethrough the funnel member 8. The cap 10 is moved to closed positionafter the radiator is filled. As vapors and steam 7 which, it will besiderable distance above the upper end of the radiator and provides arelatively large radiating surface. By reason of the fact that the metalof which the body 7 is constructed is thin it is obvious that the samewill cool rapidly,and vapors and steam enbe swung to open arise from thefluid within the radiator, they pass into the body observed, extends aconinvention a hollow and is permanently secured therei 13 having aT-head the liquid may be tering the body will be subjected to a. cooledatmosphere. The vapors and steam will therefore condense and flow backinto theradiator. Such of the steam and vapors as condense upon theunder surface of wall 8 will flowdownwardly to the lower edge thereofand drop back into the radiator.

ing having an opening Excessive pressures within the radiator will berelieved by the steam passing upwardly through the opening 9 and out ofthe body through openings 12 in the closure thereof.

The invention in its preferred embodiment is adapted for useparticularly with Fordson tractors, as their tractor equipped with thespaced bars 6 to the cover plate is usually secured. However, it isapparent that the body may be equally as well used With tractors ofother makes or types, and may, with slight variations in the details, bemade adaptable to other types of radiators used upon tractors or othermotor vehicles.

Having thus fully described my invention, 1 claim:

1; The combination with a radiator castherein and spaced bars within theradiator below said opening, of a hollow metallic body disposed uponsaid casing and closing said opening, a funnel member disposed withinsaid body, a bracket carried by said member, a bolt adis which justablycarried by said bracket and extending downwardly therethrough, a T- headon the lower end of said bolt adapted to engage with the bars of saidradiator, and a foraminous cover upon the upper end of said body.

2. The combination with aradiator having an opening therein and spacedbars within the radiator below said opening; of a thin metallic bodydisposed upon said radiator and closing said opening, a gasketsurrounding said opening and supporting the lower edge of said body, afunnel member disposed within said body, a bracket carried by saidmember, a bolt adjustably carried by said bracket and extendingdownwardly through said body, a T-head on the lower end of said boltadaptedto engage with the bars of said radiator, and a foraminous tophinged to the upper end of said body.

In testimony whereof I affix my signature.
